Fe₃O₄ nanoparticles prepared by high-temperature pyrolysis have homogeneous size as well as high saturation magnetization strength. Polyethylene glycol (PEG) functionalized Fe₃O₄ nanoparticles have excellent biocompatibility and biomolecular re-modification ability. The end of PEG has groups such as methoxy, carboxyl, and amino groups, which is convenient for coupling with specific targeted recognition molecules to construct targeted nanoprobes.
